Hi. I’m new here; as needed, please point me towards the appropriate n00b tutorial/resource/RTFM links first.
I have a Turris Omnia, (from the original Indiegogo fundraiser, though I only started using it 4 years ago). I also have a Turris MOX, with separate (?) issues; get to that later, probably in a separate thread.
I have been having sneaky intermittent “the Internet is broken again, no It’s back, no It’s broken again” issues for 2-3 years, across two different ISPs and countries (UPC in Hungary, and Ziggo here in The Netherlands), which I’m now pretty sure stem from the TO.
It mostly works fine, most of the time, and then someone on the LAN starts doing something on one machine that causes everyone to lose Internet access for 2-3 minutes, then access returns for 1-15 minutes, then gone again, up and down, sometimes for hours.
I’ve pinned down a few specific things that fairly consistently cause the issue (my girlfriend using her laptop for youtube and/or networked game-related activities, me downloading media with a BitTorrent client) … but it’s never a clear, 100%, “okay, this is the problem” cause.
We did discover that if my girlfriend accessed her youtube and gaming stuff through a VPN, the problem mostly went away (though there were–and are–other intermittent things, which we’ve mostly been unable to ID, which still trigger the problem).
About 6 months ago, Ziggo ISP or TurrisOS pushed some kind of upgrade that completely broke our Internet access, and after a couple days of back-and-forth with the ISP, I discovered on my own, that the problem was that the cz.nic DNS provider no longer worked thru my TO. I have no idea why that would suddenly become an issue (I used cz.nic exclusively, up to that point) … however, once I discovered and switched over to Quad9, everything was better (and to this day, the cz.nic DNS setting breaks our Internet … why?).
We never fully identified nor resolved the intermittent connectivity issue, though, despite multiple service calls to both ISPs.
And then, last week, I finally pulled the trigger on the major 3.x-to-5.x upgrade … and that has made the problem much worse. VPN no longer circumvents the issue, and now, both the girlfriend’s laptop and mobile phone trigger it nightly, and BitTorrent is almost useless (downloading, eg, a 20GB file, will actively download 5-20 MB in 10-15 seconds, then the Internet is broken for everyone for 3-5 minutes, then reconnect, download 5-20 MB more, and etc).
The girlfriend’s computer is a Win10 machine, phone is Android … but we have 2 other WinDoze boxes on the LAN, 2-4 other Android devices, plus a half-dozen Linux boxes of various flavors, and even an Apple tablet, and given the right phase of the moon, any one of them can trigger the issue.
I’m fairly comfortable in the terminal, and with ssh. Most of my machines are Linux, and I’m not afraid of getting into the guts of them. OTOH, I have never done any kind of command-line management of my routers, just the GUI admin tools, and I have very little knowledge of what is going on “under the hood”, beyond a generalized understanding that “it’s Linux-ish”.
I did see one other active “help” thread here that sounded potentially similar to my issue – Omnia drops a lot of packets over ethernet … maybe the same, maybe not.
So … you know … what do I do?
Danke, y gracias
ETA: Earlier today, I assigned a static leased IP to the girlfriend’s laptop. Tentatively, that appears to have helped … but, early days.
